Abstract
Machining tests based on homogeneous transformation matrix approach are relatively complex and time resuming in the mathematical modeling and the implementation of measurement and calculation. A new method is proposed to identify the kinematic errors of the rotation axis of machine tool table by machining tests based on sensitive directions. In order to identify the kinematic errors in the sensitive direction conveniently, a simple mathematical model of the kinematic errors is developed by optimizing the coordinate system settings based on basic kinematic transformation, and the sensitive direction vector was adopted to identify the kinematic errors from the machining errors of the finished workpiece. Experimental results demonstrate that the proposed method can reduce the complexity and time resuming substantially.
